Image masking

Even though RC does not have a built-in tool for editing masks, the application itself supports masking to some extent. Adding an alpha channel and masking only important parts speeds up a whole computation. Another benefit is that you do not need to use a reconstruction region to filter parts which are not important.

The alpha channel is used by features' detection as well as meshing. You can see the mask in the 2D view of an image when switched to the "Mask" (see the picture below). However, there is a need to create an image with an alpha channel outside RC.
